Radical Motorsport: Pushing the Limits of Performance

Have you ever dreamed of driving a race car on the open road? Radical Motorsport was founded to make that fantasy a reality. For over 20 years, Radical has been hand-building insane track beasts for thrill-seekers like you.

Founded in 1997 by two lifelong motorsport enthusiasts, Radical started modifying existing sports cars to create lean, mean racing machines. They soon realised they could build their purpose-built supercars from scratch. The result was the Radical SR3, an open-cockpit two-seater that could tear up tracks with the best of them.

Today, Radical offers a range of track-focused models that push performance limits. Their street-legal sportscars deliver the visceral thrill of racing with the convenience of road-going wheels. If you’re craving speed, Radical has a pulse-pounding cure. Strap in and get ready to experience extreme performance like you’ve only dreamed of. This is the cutting edge of automotive engineering, and it’s been waiting for you.

The Radical History: How Radical Motorsport Came to Be

Radical Motorsport was founded in 1997 by two automotive engineers, Phil Abbott and Mick Hyde, who envisioned a lightweight, high-performance sports car. Based in Peterborough, UK, Radical started producing kit cars before creating their models.

Radical shook up the motorsport world with their first model, the SR3. This open-cockpit roadster set five lap records and showcased what the company could do. The SR3 featured a stiff, lightweight chassis and a high-output engine, resulting in a power-to-weight ratio that blew away the competition.

Since then, Radical has gone on to produce a variety of models for both track and road use. Some of their most well-known cars include:

  • The SR8 is Radical’s most successful race car, with over 500 victories. This V8-powered beast has topped 200 mph.
  • The RXC, Radical’s first enclosed sports car. With a 650 horsepower V8, this model smashed the Nürburgring production car lap record.
  • The SR1 is an entry-level roadster perfect for track days and amateur racing. Despite its lower power, the SR1’s low weight still allows it to accelerate from 0 to 60 mph in just 2.8 seconds.

More than just fast in a straight line, Radicals are engineered to be handled like proper race cars. Their responsive chassis, aerodynamic designs, and race-spec components have made them dominant in sportscar racing series worldwide.

After over 20 years, Radical Motorsport continues to stick to its philosophy of combining lightweight, high-tech materials with brute power to create some of the fastest and most thrilling driving experiences on four wheels. They’ve certainly succeeded in pushing the limits of performance.

Meet the Minds Behind the Madness: Radical Motorsport’s Founders

Radical Motorsport was founded in 1997 by two auto enthusiasts, Phil Abbott and Simon Saunders, in Peterborough, England. They dreamed of building high-performance supercars that push the limits of speed and handling.

After years of designing and engineering in a small workshop, Radical released its first model in 1999, the SR3. This lightweight, mid-engined roadster was a roaring success, holding multiple lap records at tracks around the UK. The SR3 put Radical on the map as a maker of extreme, track-focused machines.

Since then, Radical has produced over a dozen models that continue redefining performance and set new records. Cars like the SR8 have a power-to-weight ratio better than a Bugatti Veyron, and the RXC is the world’s fastest diesel sports car.

Phil and Simon’s vision of creating the most thrilling driving experiences has resonated with many speed demons and track day enthusiasts. Despite now employing over 100 people, Radical still operates from its original facility, keeping that small-company spirit at the heart of everything they do.

Over 20 years after the first Radical rolled out, Phil and Simon continue to push the envelope of automotive performance. Thanks to their drive and dedication, Radical Motorsport has cemented its place as a leader in the world of hardcore hypercars. For that, all motorsport fans should be genuinely grateful.

Radical Models Through the Years: RXC, SR3 and Beyond

Radical Motorsport has produced some genuinely extreme models over the years. Each generation pushes the boundaries of performance and handling, focusing on track-ready power and precision engineering.


The RXC was Radical’s first foray into closed-cockpit designs. Released in 2006, this mid-engine supercar boasted a top speed of 185 mph and 0-60 acceleration in just 2.8 seconds. Powered by a 3.5L Ford V6, the RXC set 5 lap records at the Nürburgring.


Radical’s most popular SR3 model is a lightweight open-cockpit track beast. First built in 1997, this lithe rocket reaches 60 mph in just 2.7 seconds. The SR3 has dominated sportscar racing, securing multiple British Hillclimb Championship titles and lap records at tracks like Spa and Silverstone. Powered by a 185-hp Suzuki engine, the SR3 offers an unparalleled driving experience for aspiring racers.


More recent Radical models like the RXC Spyder, SR1, and SR10 push power past 300 hp, allowing 0-60 sprints under 2.5 seconds. In 2018, Radical released their most extreme creation yet: the SR9. Packing a 345-hp V8, the SR9 is Radical’s fastest model, with a top speed of over 195 mph. Advanced aerodynamics generate over 1,000 kg of downforce at 100 mph, delivering a tenacious high-speed grip.

Radical Motorsport continues to redefine extreme performance. With a focus on lightweight, high-power designs, their uncompromising models offer an unforgettable thrill ride for track enthusiasts seeking the ultimate sportscar experience. Each new generation builds on Radical’s legacy of record-breaking power, precision and unbridled performance.

What Makes a Radical a Radical: Their Trademark Design and Performance

Radical MotorSport is renowned for its trademark design and high performance. What makes these vehicles genuinely revolutionary? Several key factors have defined the brand since its founding.

Aerodynamic Design

Radical’s aerodynamic designs prioritise downforce and drag reduction. Their lightweight composite body panels and open cockpit layout minimise air resistance while maximising power. This allows for blistering speed and handling. Models like the SR3 and RXC Spyder epitomise this aerodynamic approach.

High Power-to-Weight Ratio

Radical Motorsport packs a significant punch thanks to its high power-to-weight ratios. The company uses potent Ford engines in an ultra-lightweight chassis, like the 2000cc Duratec, producing over 300 brake horsepower. The result is a vehicle that can accelerate and corner at breakneck speeds. For example, the SR3 SL model has a power-to-weight ratio of around 500 brake horsepower per ton, allowing it to sprint from 0 to 60 mph in just 2.8 seconds.

Focus on Performance

Above all else, Radical Motorsport vehicles are designed for performance driving. Everything about their vehicles, from the aerodynamic composite body to the roll cage chassis and racing seats, is optimised for high performance on the track. Models like the SR3 and RXC are essentially open-wheel race cars adapted for the road. This focus on performance has earned Radical Sportscars numerous racing victories and speed records.

British Engineering

Despite their cutting-edge designs, Radical Motorsport is proudly British. The company was founded in 1997 by former racing driver Phil Abbott and design engineer Mick Hyde. Headquartered in Peterborough, UK, Radical still produces all their vehicles today using British parts and labour. This local approach and racing heritage are inherent to the brand’s identity.

In summary, Radical Motorsport is in a league of its own thanks to its aerodynamic designs, high power-to-weight ratios, uncompromising focus on performance, and British engineering. These factors have defined the brand for over 20 years of building radical road and race cars. What’s next for this innovative company pushing the limits of speed and technology? The future looks very fast indeed.
